What is R6003, R6009, ^@, ^C, ^A etc?

I don't understand the page.

Looks like the cat couldn't handle it. –  Lance Roberts Jul 12 '10 at 16:01

A simple Google of R6003 and R6009 reveals that they are both runtime errors; one is integer divide by 0, the other is not enough space for environment. I'll leave it up to you to decide which is which. The carat-prefixed symbols are control codes that were converted to ascii text. ^M is a newline, for example. Basically... it's a type of messed up error you might get trying to read a stack trace while doing some old sk00l hacking. –  Randolpho Jul 12 '10 at 16:18
    
@Randolpho: Where do these names (like R6003 etc) come from? –  Moeb Jul 12 '10 at 17:44

This is roughly what you'd see when you open an old MS-DOS program (.exe) in a text editor. They scrolled the page until something recognizable showed up. Which are the runtime errors that the Microsoft C-runtime can show when it has to abort the program due to an unrecoverable error. Like stack overflow.

The editor has a bit of trouble with some of the bytes in the file that are control codes in ASCII. Showing them with a ^ followed by a letter that's the code + 0x40, an old convention. So ^@ is 0x00, ^A is 0x01, ^C is 0x03, ^M is 0x0D (carriage return), etcetera. It displays 0x0A as-is, interpreted as a line-feed that terminates the line. Which gives clues to the editor's origin, it is a Unix editor. One way in which Unix and Dos/Windows are famously incompatible, a line-ending in Unix is "\n" but is "\r\n" in Windows. Noted by @badp, the color scheme suggests gedit was used.

Some of the runtime errors are still defined in modern Windows C/C++ programs that were built with Microsoft's C compiler. Like R6018. But not StackOverflow anymore, that's handled by the operating system today. Exception code 0xC00000FD, STATUS_STACK_OVERFLOW. Don't bother sending the error report to Microsoft, they already have a billion of them.

Those look like gedit themes. –  badp Oct 9 '10 at 13:12

It reminds me more about the old Apple ][e, when booting, displaying a screen of random characters, with ^@ for zeroes...

SO mods are trying too hard to make it look 'geeky'.

Yes, for the youngsters here it already looks geeky, for some of us, its flashbacks from the good old days, single user,single tasking, oh my.. –  neslekkiM Oct 9 '10 at 12:15
    
They don't have to try so hard, really. Just say, "We are sorry, SO is down due to ..." –  OTZ Oct 9 '10 at 12:21

Actually it's not the SO Mods. We have nothing to do with it. It is really the SO Development Team that comes up with this stuff, and in fact, there is a lot of work and discussion around it. It is what makes SO better then most other sites. But then again, you have to appreciate the site and it's history to understand that. –  Diago Oct 9 '10 at 12:32

@Diago It would be extremely hard to appreciate the site if one gets suspended for breaking rules that don't exist, can't post questions any longer on meta, receives a follow-up suspension on SO simply because a question was migrated to meta, would it? –  OTZ Oct 9 '10 at 12:39

Considering your profile, and the quality of your posts, I am extremely surprised you survived without suspension as long as you did. The rules are clearly defined in the FAQ, and you triggered the automatic banning system for bad quality questions. Honestly, the site has a high standard, and if your not willing to get better, improve and appreciate the site, it's better off not having you around. Also, when you don't even have a email in your profile, it's impossible for any mod to let you know why you got suspended. We do not discuss suspension on MSO, but your profile speak for itself. –  Diago Oct 9 '10 at 13:09
    
@Diago Thanks you very much for taking a look. While it is rare to encounter a dia-mod that says "we don't need you here," I definitely love your honesty. So automatic banning system suspended me for a week for having posted bad questions. I'll take your word for it. But you haven't mentioned the reason why I am no longer allowed to post questions on MSO and exactly why I was banned on SO yesterday in addition. Would you mind elaborating on those points please? –  OTZ Oct 9 '10 at 19:06
    
I have no idea. The automatic IP bans will not suspend your account, it will simply prevent you from posting any questions. Your account suspension on SO I cannot track because I am not a mod there, and as already mentioned no mod can contact you to tell you. It's not within my power to investigate. I simply commented on what I can see, and what would trigger my mod senses. I would suggest you read this post with regards to why you can't post questions here. –  Diago Oct 9 '10 at 19:22
